In-System FPGA Prototyping of an Itanium Microarchitecture (2004)

 

 

We describe an effort to prototype an Itanium microarchitecture using an FPGA. The microarchitecture model is written in the Bluespec hardware description language (HDL) and supports a subset of the Itanium instruction set architecture. The microarchitecture model includes details such as multi-bundle instruction fetch, decode and issue; parallel pipelined execution units with scoreboarding and predicated bypassing; and multiple levels of cache hierarchies. The microarchitecture model is synthesized and prototyped on a special FPGA card that allows the processor model to interface directly to the memory bus of a host PC. This is an effort toward developing a flexible microprocessor prototyping framework for rapid design exploration. [via]
